I am a Postdoctoral Fellow at the Immigration Policy Lab at Stanford University . I am supporting the Lab’s Migration and Development Initiative to better understand and find policy solutions for the challenges of displaced persons in developing countries.

In my research, I explore how households make decisions to move or flee under high risks like conflict, poverty and climate-induced stress. I am particularly interested in questions such as: how do civilians make the choice to flee, how do governments and other actors respond to displacement on the local level, how can we predict (forced) migration in light of changing conflict patterns and development challenges, and what impact does human mobility have on societies in the Global South? I predominantly use quantitative methods - spatial statistics, machine learning but also survey experiments and randomized control trials - in my work. I have conducted several surveys in the context of Iraq, Myanmar and the Democratic Republic of the Congo. Beyond my research agenda on forced migration, I am interested in conflict dynamics, refugee policies, statelessness, and civilian resilience in fragile settings.

I have received a PhD in Political Science at the Department of Political Science , University College London (UCL) in 2023. I have previously worked as consultant for the World Bank-UNHCR Joint Data Center on Forced Displacement . I completed a MSc in Security Studies at UCL and a BA in Politics and Public Administration at the University of Konstanz, Germany. You can contact me at sigweber@stanford.edu.

My research more generally addresses issues in International Relations, comparative politics, migration and conflict research.

Understanding household-level decisions around human mobility

In one current stream of my research, I am interested in household-level decision making around fleeing, moving and migrating. Although most of my research focuses on internally displaced persons, I more broadly investigate when individuals decide to flee, what conditions shape where they are seeking shelter, in what type of host communities they want to live and when they return home.

For more information:

Forced migration decision-making : How do individuals decide to flee and how do patterns of violence affect these decisions?

IDP hosting preferences : How does past exposure to violence and displacement affect the willingness to help others by hosting displaced persons?

IDP returns and property rights : How do housing, land and property rights affect return decisions of internally displaced persons?

Conflict dynamics and social cohesion in conflict-affected places

Related to my research on displacement, I am interested in better understanding conflict as a cause of flight. This includes understanding micro-level patterns of violence or thinking through how armed actors interact with displaced persons that move through their territories.

For more information:

Territorial takeover and civilian targeting : Do rebels target civilians as part of the process of establishing control in newly captured territory?

Armed actors and displacement : How do armed actors respond to population movements during civil wars? How do population movements change violent dynamics during war?
